These alterations include the development of over 5900 km of levees in addition to operation of dams and flood control structures designed to manage river stages for navigation and/or to prevent flooding. Fig. 1 Theoretical hydropatterns for an alluvial swamp forest (upper panel) and hardwood ...
Silver carp invaded eastern South Dakota tributaries of the Missouri River in the early 2000s. Changes in dynamic rate functions can occur as invasive populations move to the latter stages of the invasion curve, but direct temporal assessments of silver carp populations ar...
Survival from larval to young-of-the-year stage (June through August) was highest during 1991 due, in part, to the recent drought. Reduced fluctuation of river stages occurred as a result of reduced runoff, which minimized the need to reduce discharge to prevent flooding in the lower basin....
In a relationship, it is known that the beginning is the most euphoric and is often referred to the honeymoon stage. After the bliss is gone and the flaws start to show, overtime the couple may realize that the relationship is not worth salvaging. The stages in a relationship can be ...

In fact, increased stages in the years prior to the post-carp sampling could have facilitated bigheaded carp establishment in these particular oxbow lakes. Stages were equally variable between the two periods, however, this degree of hydrologic increase as it might influence river–lake connectance...
stages of the navigation-improvement program include a channel 9 feet (2.75 metres) deep and 250 feet (75 metres) wide at low water betweenCairo,Illinois, andBaton Rouge,Louisiana, authorized in 1896; a widening of this channel to 300 feet (90 metres), approved in 1928; and its deepening...
Accompanying the last two stages of glaciation were extensive deposits of windblown silt, or loess. Over the millennia, the prevailing west winds carried the loess from the western plains into Iowa as the glaciers retreated. In extreme western Iowa the loess deposits accumulated to form what are ...
Water level fluctuations of 5 m to 10 m are common as river stages fluctuate between seasons. The main source of recharge to all aquifers is precipitation and water applied for irrigation [19]. In the Athani Taluka, the annual recharge is in the range of 100 mm to 150 mm [20]. 2.2....
